Abstract: A display device includes: a display panel including first and second display areas adjacent to each other; and first and second data drivers configured to drive the first and second display areas, respectively, wherein the first data driver includes: a first afterimage detector configured to receive an input image and to detect a first afterimage area including an afterimage of the first display area from the input image; a first comparator configured to compare an afterimage detection result of the first display area with an afterimage detection result of the second display area received from the second data driver; and a first coordinate corrector configured to correct coordinates of the first afterimage area in response to the afterimage detection result of the first display area and the afterimage detection result of the second display area satisfying a preset reference.

Abstract: An afterimage detection device includes a downscaling unit that downscales an input image at a preset ratio, an image accumulation unit that receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image, an afterimage detection unit that detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information, and a weight applying unit that receives the afterimage information, calculates a downscaling weight of a region of interest including the afterimage in the input image based on a time parameter, and provides the downscaling weight to the downscaling unit.

Abstract: A method for displaying an image using a display device includes generating first image data corresponding to a first image displayed in a first area in an image display area, differently determining the size of a second area in which a second image is displayed corresponding to shift information of a preset image, generating second image data corresponding to the second image, based on the first image data, generating a data signal, based on the first image data or the second image data, and emitting light with a luminance corresponding to the data signal.
